FOREST M. LAMPSON AND GEORGE W. HOGBEN, OF RIPON, WISCONSIN.

ADJUSTABLE WINDOW-SCREEN.

SPECIFICATION forming part; of Letters Patent No. 328,691, dated October 20, 1885.

Application filed May 18, 1885.

T 0 all whom it may concern.-

Be it known that we, FOREST M. LAMPSON and GEORGE W. HOGBEN, both residents of Ripon, in the county of Fond du Lac, Wisconsin, have invented a new and Improved Adjnstable \"indow-Screen, of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved window-screen which fits window-frames of different widths.

The invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a front view of our improved window-screen held in a window-frame. Fig. 2 is a sectional plan View of the same on the line a: m, Fig. 1.

The window-screen A is of the usual construction, and on each end of the same an upright strip, B, is placed, on the inner surface of the frame of the said screen. V-shaped springs 0 have their ends secured on the outer surfaces of the strips B, and their inner ends or the apex secured on thescreen-fraine, which springs press the said strips B to the ends of the screen-frame and against the jambs of the window-frame D. \Vires or pins F, projecting from the inner edges of the strips B, rest on the screen-frame, and are guided by staples G driven over the wires F into the screenframe. The free ends of the wires F are bent to prevent the springs from pressing the strips Serial No. 165,934. (No model.)

from the ends of the screen-frame so far that the inner edges of the strips are beyond the ends of the frame. When the screen-frame is placed in a narrow window-frame, the strips B overlap the end pieces of the screen-frame a greater dis tance than when the screen is placed in a wider window-frame. In all cases the outer edges of the strips B. are pressed against the jambs or inner sides of the standards of the window-frame and form close and tight joints.

We are aware that screens have been heretofore provided with strips forced outward by springs to adapt them to fit window-frames of different widths. We are also aware that the spring-pressed strips have been provided with headed guide-pins, and we are further aware that V-shaped springs are not broadly new, and wetherefore do not claim such inventions.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent As an improved article of manufacture, an adjustable window screen consisting of the screen-frame A, provided with the staples G, the strips B, arranged at the side of the end portions of the said frame and projecting beyond the same, headed pins secured to the strips and working in the staples of the frame, and the V-shaped springs 0, having their ends secured to the strips and their apices t0 the screen-frame, as set forth.
